Again that is strained interpretation of the OT based one what the authors of the NT claim. Read without the NT the 'seed' does not imply JC.Going all the way back to the fall of man men have known of the promised " seed "
Err not true.Every religion that sprouted up knew of that and used it to create their own versions
The Gospel began with that prophecy and it remains intact to this day by the fulfilling of it in Jesus Christ. So, when Paul visited your friends in Greece he remarked to them that they worshipped many gods but that they missed out on the real One which they named the unknown God.
The author of Acts is playing a game. A sophism quite worthy of his location. The alter if it existed at all (where the dramatic action of the texts place) was to unknown gods. A fair bet is it was (if extent) meant to placate the Erinyes and probably also more generally to acknowledge the small local gods that were bound to things springs and such across the land that Athens ruled (to be on the the asparagus hill would have to been to the oldest gods of Athens). More firmly according to Pausanias There were multiple shrines to unknown plural gods in the harbor at Phaleron. But dedicated randomly to heroes, other gods (plural) unknown gods (plural) the Children Theseus, etc. Another again plural shine is noted by Hesychios at Athens arising out of some mythical incident after the Trojan war that involved killing on Athenian soil and so a shine was set to deflect responsibility. (Athenians killed their former allies in the War or some such possibly with shady justifications).
Its a nice passage you cite however that even has no more than a Roman university town Athens retained its open mindedness. But there was simply no single one unknown god (male at that). But this is similar to the seed reference very cleaver people bending data to the will of the NT. Be it the OT, or in this a pleasant little passage about famous Athens and it supposedly have been waiting about for one unknown god. Too bad the christian emperors of later days and their bishops could not show the same courtesy to the academies at Athens or fail to pillage its temples as it showed Paul.
Shines to other gods are found and do seem to have been a thing in the heterogeneous Hellenist Greek world.
Still represents than a capricious god for at first damning the whole world for the acts of two people and than only allowing salvation in a scatter shot way that implicitly meant thousands would live and die with out an opportunity to get the message.As long as you remain in your sin you are evil. There's no use saying, " but I am a good person," when it is written that there is none good, only God and that's why God in Jesus Christ came into the world
So no particular reason Jesus could not have shown up being born from Eve and this over with at the beginning. Or been one of Lots kid's or Noah's and been persecuted than?Someone may be able to pay for our sin in His own blood. Yes, blood that was never tainted by sin, therefore the only blood that could satisfy the demands of the Law.
